The BBC iPlayer Home page (www.bbc.co.uk/iplayer) includes tiles referred to as Collections. The idea is you mouse-over the tile and an animated list of available programs is displayed.
You might well ask, what has this to do with Surface Book? Well, using MS Edge on the Surface Book, when you mouse-over the tile, the animated list doesn't appear, the mouse pointer becomes erratic, and the Surface Book becomes sluggish to respond. Neither Chrome nor FireFox have this issue.
Here's the oddity: I can use MS Edge to open iPlayer Collection tiles on two other Win 10 machines with no problem.
Does this imply a driver or graphics controller issue specific to the Surface Book?
